Explanation of Responses:

1. On March 1, 2016, the Reporting Person was granted a Performance Stock Unit ("PSU") award of 2,719 PSUs. The PSUs convert into common stock on a one-for-one basis, and vest in three equal annual installments beginning on March 1, 2017 based on the Issuer's satisfaction of certain performance criteria for the fiscal years ending December 31, 2016, 2017 and 2018. On February 7, 2017, the Compensation Committee of the Board of Directors of the Issuer certified that the performance criteria for 2016 was met, resulting in vesting of PSUs as to 724 shares on March 1, 2017.

2. Includes 15,347 Restricted Stock Units (each, an "RSU") that are subject to time-based vesting and will be settled only in stock. The unvested RSUs were previously reported by the Reporting Person as derivative securities. Effective March 1, 2017, the Reporting Person has determined to report RSU awards that are subject to time-based vesting and only settled in stock as non-derivative securities in his ownership reports.

3. 11,035 of these securities are units of common stock granted pursuant to RSU awards. The units are subject to time-based vesting.
